The social activist – who was married to Madonna from 1985 to 1989 and to Robin Wright from 1996 to 2010 – told an interviewer two years ago that many of his relationships were a “fraud” and that he never felt loved.

Now Charlize’s pals are warning the actress to guard her heart, revealed a source.

“They’re urging her to think twice before finally heading down the aisle with Sean.”
